Ganache teaches sorcery at Micro-Grand Academy, instructing students in magical rituals like summoning tree spirits or faeries. During one ritual, student Cacao consumed expired magical chocolate, causing intoxication that disrupted the sacred circle. This disruption triggered an explosion and allowed the summoned spirit Hinano to escape, inhabiting a nearby marionette puppet instead of its intended vessel. Ganache later explained the incident to Cacao, securing the student's reluctant agreement to become his magic apprentice in exchange for this information. He persistently attempts to teach Cacao magical techniques, achieving minimal success due to Cacao's lack of interest and aptitude. Ganache maintains professional relationships with other academy staff, including Professor Big Bang and Professor Papaya. He also maintains an ongoing antagonistic relationship with Mozzarella, identified as Truffle's grandfather and the series' primary antagonist. This rivalry forms a recurring element of conflict. Ganache is also known by the name Ganache.
